| `context`   | [models.ReasoningContext](../models/reasoningcontext.mdx)                   | :heavy\_minus\_sign: | Controls which reasoning is available to the model. `auto` uses the model default (same as omitting); `all_turns` includes reasoning from earlier turns passed in input; `current_turn` limits to the current turn only. Only supported by OpenAI GPT-5.6 and newer. | all\_turns |
